The title is complete clickbait. It should say “no one’s short intuitive explanations of why planes stay in the air are fully correct”

Exactly. Like many things in physics there are simple answers, there are correct answers, and there's a sliding scale between the two.

Not 'fully correct' there are also simple/correct answers and complex/incorrect answers.

I'd say reaction force is a sufficient explanation. The wing compresses the air column below it. The pressurised air generates buoyancy sufficient to dynamically support the air craft while moving at a high enough speed.

And unless you cross over to supersonic regime it's completely wrong (^_-)

Ok. Why? See if this is an educational discussion it makes sense to support one's argument, not just say no, you're wrong...I supported my argument with a plausible explanation.

If planes are not supported by the air beneath them pushing up why don't they fall out of the sky?

There are simple experiments you can perform to prove the correctness of Bernoulli’s principle. If the math cannot accurately describe completely what is happening, then it is our math that is lacking. Technically the air is less dense on top which generates lift. And yes planes do fall from the sky when they stall due large angles of attack which disrupt the laminar flow.
